Re^2: From Perl to Java

Any proofs regarding the execution speed difference? I bet there was a lot of improvement over the years in the Java world from the notoriously insanely unusably fat and slow language of late 90s, but there is very little reason for Java to ever be quicker than Perl.

but there is very little reason for Java to ever bee quicker than Perl. I guess with JIT compilation and smart optimizers you can get very good speed improvements, inline method calls and stuff like that. Since perl 5 has not JIT, many possible optimizations can't be made. But I don't know which is actually faster in what cases. Maybe the Debian language shootout has some answers, but at the moment I'm too tired to interpret the results ;-)	[reply]
